6.9.4 Adjusting and Controlling the Alpha Micro
The Maintenance submenu lets you control the Alpha Micro and change selected items to meet your operational
needs.
Procedure
From the Main menu, type 3 and press Enter.
Table K — Maintenance Submenu
30 Battery Test Options This starts the battery test and sets how long the test will run. The default setting for the
test duration is 2 minutes, but this can be adjusted in 1 minute intervals. See "Operating
the Alpha Micro, BATT TEST”.
31 Inverter On/Off This switches the inverter on or off to allow you to prevent a damaging deep battery
discharge or to provide backup battery power to the load. See “Operating the
Alpha Micro INVERTER”.
You can set a delay before the inverter switches off to allow time for switching off critical
loads. The Set Inverter ON/OFF delay is only available when the Alpha Micro is in the
Battery or Standby modes.
The delay can be adjusted in 1 second steps with a default setting of 0 seconds to a
maximum of 600 seconds (10 minutes). The delay is only available in the Standby or
Battery modes. Once the Alpha Micro returns to the Line mode, the delay resets itself to 0
seconds.
32 Change Password This changes the Alpha Micro’s password. The factory set password is 1111, which can
only be changed when the Alpha Micro is in Line mode. The password is limited to 4
alpha-numeric characters in length.
34 Line Qualify Time This lets you set the delay when the Alpha Micro goes from Battery mode to Line mode
after the line becomes requalified. The purpose of this delay is to make sure the line is
stable before the Alpha Micro switches back to it. See “Operating the Alpha Micro, QUAL
TIME”.
The default setting is 3 seconds, but you can set this to 3, 10, 20, 30, 40 or 50 seconds.
35 Low Battery Warning
Voltage
The lets you set the Alpha Micro’s low battery warning voltage, adjusting the setting to
match the batteries you are using and the actual operating conditions.
The default value is 40% (47 VDC) and can be adjusted in 1% (0.05 VDC) increments
between 45.0 (0 %) and 50.0 VDC (100%) by typing in the % battery voltage level where
you want the warning to be triggered.
36 Load Shed Timer On/Off This lets you switch the timer contacts on or off. See "Contacts C1 to C6”.
